The worst-to-first Boston Red Sox are going back to the World Series for the third time in the last decade.

With the stain of last season’s 69-win disaster now a faded memory, its place taken by a team populated with new heroes like Shane Victorino and Xander Bogaerts, the Red Sox dismissed the Detroit Tigers 5-2 in explosive comeback fashion Saturday to win the American League Championship Series in six games.

With the Red Sox trailing 2-1 in the seventh inning, Victorino’s second career postseason grand slam put Boston over the top and touched off a wild celebration in Boston’s Back Bay area.

Meanwhile rookie Bogaerts, who was inserted into the lineup after the fourth game, doubled and scored twice and proved to be a momentum changer in the series, going 3-for-6 with four walks in his three starts.
